MANUFACTURE. OF PATTERNED LINOLEUM.

SPECIFICATION forming part of Letters Patent 0. 718,4:77, dated January 13, 1903.

Application filed November 2'7, 1900. Serial No. SL899. (N specimens.)

To all whom it may concern:

Be it known that we, KARL KLIO, artist, a subject of the Emperor of Austria-Hungary, residing at XIII Anhofstrasse 18, in the city of Vienna, Austria-Hungary, and OSCAR POPPE, general director, a subject of the German Emperor, residing at Rixdorf, near Berlin, Germany, have invented new and useful Improvements in the Manufacture of Pat- [0 terned Linoleum, of which the following isa specification.

Our invention relates to the production of inlaid linoleum of a wood-grain effect, such grain extending through the whole thickness 1 5 of the material. Attempts have been made to obtain such effect by passing coarselygranulated linoleum material of various colors between rollers, by which thin sheets or leaves are formed, the various particles of the mass being pressed until they assume the shape of longish leaves. The efiect, however, is coarse and indistinct, since the flat sides of such leaves are exposed to view. This objection is overcome by the present invention, the carrying out of which involves the placing of strips formed from coarselygranulated linoleum material of various shades, which material has been passed through suitable presses or roller-cylinders one upon another and cementing the same together by a suitable adhesive, preferably formed from linseed-oil, cement swelled or brought to a gummy condition in benzol or the like and finally triturated, each of said 3 5 strips being composed of various shades and being of different shades from the next contiguous sheet on either side. The block thus obtained is cut transversely into strips or plates of required thickness either perpendicularly or obliquely to the surface of the original plates, so that the edges of the original plates will form the faces of the finallyproduced plates, and it will be found that, according to whether these cuts are parallel with or perpendicular to the direction in which the plates passed through the pressercylinders, the cut surface edge will represent a grain very similar to wood, and especially to oak, having the appearance of wood cut longitudinally in the first instance and transversely in the second. This effect is obtained owing to the various small leaves or plates forming the complete block being cut through their thickness, so that the linoleum particles represent a delicately irregular pattern of approximately parallel lines of various thicknesses and shades.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A sheet of linoleum composed of a multiplicity of sheets, having their edges secured together to form a flat sheet, and the sheet representing a through-grained pattern similar to wood, substantially as described.

2. The process of manufacturing a sheet of Wood-grained linoleum, comprising forming sheets of granulated linoleum of various shades, the various particles assuming the shape of longish leaves, assembling a plurality of such sheets by placing one upon another, securing said sheets together and cutting plates from the block thus formed transversely of the original sheets, substantially as described.

3. The process of manufacturing a sheet of wood-grained linoleum, comprising forming sheets of granulated linoleum, each sheet containing various shades, said sheets being of various shades with respect to each other, the various particles composing each sheet assuming the shape of longish leaves, assembling said sheets by placing one upon the other, securing the sheets thus assembled for forming a block, and cutting plates of linoleum from said block transversely of the original sheets, substantially as described.

4. The process of manufacturing a sheet of wood-grained linoleum, comprising forming sheets of granulated linoleum material, each sheet being formed of various shades, the particles composing each sheet assuming the shape of longish leaves, assembling said sheets one upon the other and securing the same together to form a block, each sheet differing in shade from the contiguous sheet,

and cutting plates of linoleum from the block formed from said assembled sheets transverse the sheets, substantially as described.

5. The process of manufacturing a sheet of wood-grained linoleum, comprising forming sheets of granulated linoleum material, the particles forming each sheet assuming the shape of longish leaves, assembling said sheets one upon another and securing the same together for forming a block, each sheet being formed of varied shades, and differing in shade from that of the next contiguous sheet upon each side, and cutting plates of linoleum from the block formed of the said assembled sheets transverse the sheets, substantially as described.

6. The process of manufacturing a sheet of Wood-grained linoleum, comprising forming sheets or plates of linoleum material of various shades, the various particles of each sheet assuming the shape of longish leaves, the grains of said sheets extendingin the same direction in parallel lines, securing the sheets together one upon another parallel to each gether for forming a block, and cutting plates 35 therefrom, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
